F13 640i xDrive front left shock absorber Bilstein B4 22-295323

The Bilstein B4 22-295323 is a direct-fit, gas-pressure twin-tube damper for F13 640i xDrive, 650i xDrive and 640d xDrive (2011-2017). No mods. No spacers. Just bolt-on damping that’s stiffer than stock but still civilised for daily driver or fast road use.

• Replaces OE part for F13 chassis with N55, N54 or N47 engines - not for M6 (F13) or non-xDrive models
• Compatible with stage 1 and stage 2 setups where you’re keeping OEM springs and alignment specs
• Works with track day duty if paired with supportive springs and regular fluid checks - not a race-spec unit, but more consistent than worn originals
• Pair with 22-295330 for full front axle refresh; avoids mismatched damping on fast road or show car builds
